I recently changed the heater core & the car puts. Out heat, but after a few seconds the vent door closes. I can hold the switch and force it to stay open, but I am afraid to damage something. Is there a part that may be replaced to allow the vent door to stay open while heater is on?

Are you talking about the actuator for the dash?

Note the vacuum diagram for hvac. The actuator may be losing vacuum?
